INKING MACHINE.

Application filed November 7, 1919. Serial 1%. sa e.

To all whom it may concern.

Be it known that I, somuoa H. Gorin- BERG, a citizen of the United statearesiduig in the city of Chicago, county of (look, and State of Illinois, have invented certain new and useful- Improvements in Inking Machines, of which the following is a specification.

My invention relates to inking machines and has for its salient objects to provide a machine which will. automatically supply printing ink to a typing block and applythe same ina uniform film; to provide a ma; chine of the character referred to in which the ink feed may be cut ofli at any time and the ink supplied from that which has collected on the distributiiig rolls; toprovide a machine in which the inking roll passes over the printing block before each printing operation. 7

It relates more particularly to a machine for puttingprinted matter, symbols orfig? ures upon paper tubes which are subsequently cut into bands. The inking mechanism which is the feature of my invention is used in combination with a cutting. device which is the subject of a former application, Serial No. 266,670, filed Dec. 14, 1918, and will be explained and described only in so far as it is necessary to an understanding of the inking mechanism.

In the drawings:

Fig. 1 is an end elevation, partly in cross section, of the inking machine in combination with the tube cutter.

Fig. 2 is a sectional detail of the inking: mechanism.

Fig. 3 is a fragmentary detail view of the driving parts for the inking mechanism.

Fig. 4 is a fragmentary detail View of one of the rods with a tube thereon.

Fig; 5 is a sectional view of tube and rod shown in Fig. 4. V

Referring in detail to the drawings, the

machine frame 1 is inclined at 2 to form a feeding chute for the hollow tubes 3, which are placed upon wooden rods 4, shown more clearly in Fig. 2, the weight of the rods assisting in their being fed down the inclined surface and furnish a solid cylinder for the printing and cutting members to operate against.

On a shaft 5 journalled in suitable bear ings 6, which are fixed to the machine frame 1, by means of the supporting plate 7, is

mounted a cam 8'. This cam in rotating contacts with a roller9' o n the'bottomofthe stop 10, which is pivoted to the frame at 11 The stop is held in position by a tension spring 12' fastened to a stud 13 on the frame by any suitable means, such as the heavy wire link 14. A rounded contact member 15 mounted on theend of aprojection 16 ofthe stop 10 operates against the' lower end 17*, of a second stop 17. The stop 17 is pivoted at 18 to the frame 1 and when a tube is released by stop 10 to pass through the machine, the stop 17is forced upward by com pression'spring 19, being free to move when projection 16 moves from its lower member actuated'by cam' 8; The compression spring 19 is set in a block 20 which in turn is fastened to the inclined frame 2. The stop 17 comes up in front of the'second tube, therebypreventing it and subsequent tubes fromfollowing the first tube which was released to. proceed through the machine. over the top of the tubes keepfthem position on the inclined chute and preveiit overriding. The lower end of the strips'21 are bent down to assist secondary stop 17.

Fixed also to the shaft 5 is the'fee'd roll 22 which has the inking roll 23' mounted on shaft 24 arranged in an aperture 25, in the surface of the roll 22 so that thesurfac'e of the small inking roll extends beyond the surface of the feed roll. The feed roll is driven from a sprocket 26: on shaft 27, a chain 28 and sprocket 29 on shaft 5. The rotation of this roll feeds the tubes under the type 30 in the block 30 which may be printed letters, or design figures, and in scribes same on the surface of the tube as shown in Fig. 4. The printed matter may be duplicated according to the width'of the machine and width of band to'be cut, as shown in Fig. 4, so when out a number of bands may be made from the same tube.

The tubes, after passing between the printing block and feed roll drop through chute 31 onto the roll 32 which is fixed to shaft 26 and is rotated by any suitable power (not shown) through pulley 33. This roll 32 feeds the tubes against the series of cutting blades 34 set in slots 35 provided in block 36, which sever the tubes into narrow bands 8 shown in Fig. 4. After cutting, the rods with the narrow bands thereon, drop onto the collector 37' where they are gatheredup and the bands removed from the rods.

To return to the printing arrangement,

7 the block 30 is fastened to the arm 38 which is pivoted on the shaft 39, while the opposite end 38* is restricted in its movement by the Which holds the shaft 39. A weighted cross bar 42' fastened to the arm 43 and similar arm on the opposite end of the machine (not shown) pivoted to the supporting plate 7 at 44, is adjusted by screw 45, rides upon the top of a round headed stud 46. A compression spring 47 that surrounds the stud and is set in a hole in the arm 38 absorbs the'shock of the weight 39, as the printing block rides over the tubes.

The ink shown at 48 in Fig. 2 is contained in a cylindrical reservoir 49, which has a number of perforations 50 c in its shell. These holes or perforations are small and the heavy ink does not readily seep through them. The reservoir is rotatably mounted on the shaft 51 carried by a flange member 52, pivoted at 53 to a projection l offrame 1. A hook 54 at the lower end of flange 52, through a tension spring 55 fastened to frame 1' at stud 56,- keeps the cylindrical reservoirincontactwith the lower distributing roll 57, when it is desired to ink the distributing rolls. A latch 58, pivoted to projecting frame 1 engages a pin 59 on the flange '52, holds the reservoir out 'of contact with the distributing roll when a sufficient amountof ink has been fed to the distributing rolls. For the purpose of feeding the ink: through theperforations in the reservoir, awroll 60 isloosely journalled in the lower end of an eccentric member 61, which is fixedly. attached to the shaft 51 by means of the ,pin 62. The roll, being loosely journalledj and having its outer surface very intimate with the inside surface of the reservoir forces the ink through the perforations onto the outer surface of the larger cylinder 49.

p The distributing rolls 57 and 63 are of a gelatinous substance similar to the inking roll 23. They are mounted on shafts 64 and 65- respectively, which are carried by a secondary frame member 1*. The shaft 65 and roll 63 are driven from the shaft 5 by means of gears 66 and 67, as shown in Fig. 3. The roll 57 is rotated by roll 63, and roll 49 by roll 57, due to the frictional contact of theirrespective outer surfaces.

The course of the ink is as follows: After being forced through the small perforations in the reservoir 49 to the outer surface,-it is rolled. upon the surfaces of thegelatinous distributing rolls 57 and 63. As the feeding drum 22 rotates, the inking roll 23 will contact the surface of the upper distributing roll 57 and collect someof the ink from its surface. As the feed roll 22 continues to rotate, the inking roll 23 will transfer some of the ink to the printing type. When the tubes are fed under the type by the feed roll 22, the imprint of the type will automatically be transferred to the tubes after which they are cut into bands by the cutting device.

I claim as my invention:

1. In an inking machine, the combination with a cylindrical rotatable ink reservoir having small perforations in the periphery thereof, of means for forcing the ink to the outside surface of the ink reservoir, distributing means frictionally contacting the ink reservoir, a feed roll with an inking roll rotatably mounted thereon, said inking roll adapted to procure ink from the distributing means and printing means positioned relativeto the travel of said inking roll whereby the ink is transferred from the distributing means to the printing means.
